DFW? What a horrible experience for you! Fifty dollars may not be a fortune but it's sure more than I would want to lose, particularly in such a fashion. I am glad the thief was caught on tape.

It makes me sad to learn that this happened at *my* airport. All in all, I find the TSA at DFW to be friendly, professional, and courteous. It is a shame to learn that there is (was?) such a bad egg there.
